Provides utility methods related to element focus, without the need to handle focus-related events.
Assembly: System.Windows (in System.Windows.dll)
Thetype exposes the following members.
Windows Phone focus has the characteristic that while the focus-reporting events GotFocus and LostFocus are raised asynchronously, the focus returned by GetFocusedElement is determined synchronously. This design attempts to loosen constraints on runtime adjustments to element trees that could result from having to wait for the focus to be determined and moved. For cases where determining the synchronous focus is critical, use the GotFocus and LostFocus events as a cue, but then call FocusManager.GetFocusedElement to verify the synchronous focus.
